A smartphone is a portable computing device that combines a mobile phone and computing functions into one. They are distinguished from regular phones by stronger hardware capabilities and extensive mobile operating systems that enable a wider range of software, internet (including web browsing over mobile broadband) and multimedia functions (including music, video, cameras and gaming) in addition to the basic phone. its typically contain a variety of metal-oxide-semiconductor (MOS) integrated circuit (IC) chips, including a variety of sensors that can be exploited via pre-included and third-party software (such as magnetometer, proximity sensors, barometer, gyroscope, etc.) . accelerometer and others) and support wireless communication protocols (such as Bluetooth, Wi-Fi or satellite navigation).
Its Marketed primarily to the enterprise market, earlier smartphones attempted to bridge the functionality of stand-alone Personal Digital Assistant (PDA) devices with cellular support, but were limited by their bulky form factor, short battery life, slow analog cellular networks, and immaturity. wireless data services. These problems were eventually solved by the exponential scaling and miniaturization of MOS transistors down to submicron levels (Moore’s Law), the improved lithium-ion battery, faster digital mobile data networks (Edholm’s Law), and more mature software platforms that allowed mobile device ecosystems to evolve independent of providers give.
In the 2000s, NTT DoCoMo’s i-mode platform, BlackBerry, Nokia’s Symbian platform, and Windows Mobile began to gain ground, with models often featuring QWERTY keyboards or resistive touch input and emphasizing access to push email and wireless Internet. Following the rise in popularity of the iPhone in the late 2000s, most smartphones featured thin, slate-like form factors with large capacitive screens that supported multi-touch gestures instead of physical keyboards, offering users the ability to download or purchase additional apps from a centralized store and use cloud storage and synchronization, virtual assistants as well as mobile payment services. Smartphones have largely replaced PDAs, handheld/palm-sized computers, portable media players (PMPs) and, to a lesser extent, handheld video game consoles.
In the third quarter of 2012, one billion smartphones were in use worldwide. Worldwide sales of smartphones surpassed sales figures for feature phones in early .
iPhone 11 Pro
iPhone 11 pro and iPhone 11 Pro max are developed by Apple company. They served as the flagship models of the 13th generation of iPhones, replacing the iPhone XS and iPhone XS Max upon their launch. Apple CEO Tim Cook unveiled the device along with the standard model, the iPhone 11, on September 10, 2019 at the Steve Jobs Theater in Apple Park. Pre-orders began on September 13, 2019, and the phones went on sale on September 20.They ceased production on October 13, 2020, following the announcement of the iPhone 12 and iPhone 12 Pro.
Notable improvements over previous devices include a triple-lens rear camera system and an A13 Bionic chip. The 11 Pro and 11 Pro Max are Apple’s first iPhones to carry the “pro” designation, previously only used for larger Apple devices such as the iPad Pro and MacBook Pro. They are also the first generation of iPhones to include a Lightning to USB-C cable that allows connection to a charger and current Mac computers in the box.
The iPhone 11 Pro and 11 Pro Max are available in gold, silver, space gray, and midnight green, a new color not previously available on the iPhone. Similar to the iPhone XS and XS Max, there’s a display cutout on the front that houses the 12MP True Depth camera system and speaker. There is also a new rear camera design with three lenses and a flash in a larger square bump, which is the most visible difference from the iPhone XS. The Apple logo is now centered on the back of the device with no text, and the glass has a matte matte finish, as opposed to the glossy finish found on other glass-backed iPhones.
These Both the iPhone 11 Pro and 11 Pro Max have an A13 Bionic processor. Both phones have three internal storage options: 64GB, 256GB and 512GB and have 4GB of RAM. Both models are IP68 water- and dust-resistant and are resistant for 30 minutes at a depth of 4 meters. The warranty does not cover water damage to the phone. Continuing the trend set by the iPhone 7, neither phone includes a headphone jack, but it did come with wired Ear Pods with a Lightning connector before Apple decided to stop including them in October 2020, citing environmental impact. The iPhone 11 Pro and Pro Max are the first and only iPhones to be sold with an 18-watt USB-C fast charger.
iPhone 11 Pro has a 5.85-inch (149 mm) (sold as 5.8-inch (15 cm)) OLED display with a resolution of 2436 × 1125 pixels (2.7 megapixels), while the iPhone 11 Pro Max has a larger 6.46-inch ( 164 mm) (sold as a 6.5-inch (17 cm)) OLED display with a resolution of 2688 × 1242 pixels (3.3 megapixels). Apple describes the display as a “mini Apple Pro Display XDR” on the phone. They also have True Tone and a wide color display with HDR support with a standard brightness of 800 nits and a maximum brightness of 1200 nits when needed. The screen has an oleophobic coating that is resistant to fingerprints.The display of the iPhone 11 Pro and iPhone 11 Pro Max is manufactured by Samsung.
It becomes iPhone 11 Pro comes with an 11.67 Wh (3,046 mAh) battery, which is a slight increase from the 10.13 Wh (2,658 mAh) of the iPhone XS, while the iPhone 11 Pro Max has 15.04 Wh (3,969 mAh) battery. a slight increase over the iPhone XS Max’s 12.08 Wh (3,174 mAh). Both batteries are not user replaceable.
Two features of iPhone 11 Pro and Pro Max feature a 12MP triple-lens rear camera. There is one ƒ/2.4 ultra-wide-angle lens with a 120-degree field of view and 2x optical zoom, one ƒ/1.8 wide-angle lens and one ƒ/2.0 telephoto lens with 2x optical zoom.
There is a continuous shooting mode, image stabilization, HDR and Portrait mode supporting depth control and advanced bokeh effect. iPhone 11 Pro also has an automatic night mode, which allows the camera to take brighter images with reduced noise in low-light environments. There’s also a redesigned camera app that adds new features like a scroll wheel to choose between different lenses and a long press on the shutter to take video. Apple also announced a new Deep Fusion feature that will use AI and machine learning for image processing.
